Clinical Study on the Treatment of Cold- Dampness Stagnation Type of Dysmenorrhea with Shaofu Zhuyu Decoction Combined with Thunder-Fire Moxibustion

Objective: To investigate the therapeutic effect of Shaofu Zhuyu Decoction combined with Thunder-Fire Moxibustion on patients with cold-dampness stagnation type of dysmenorrhea. Methods: A total of 40 patients with cold-dampness stagnation type of dysmenorrhea who visited the hospital from January 2023 to December 2024 were selected as samples and randomly divided into two groups using the lottery method. The observation group received Shaofu Zhuyu Decoction combined with Thunder-Fire Moxibustion, while the control group received Shaofu Zhuyu Decoction only. The efficacy, pain score, menstrual volume, menstrual duration, symptom score, and adverse reactions were compared between the two groups. Results: The efficacy of dysmenorrhea treatment in the observation group was higher than that in the control group (P < 0.05). After treatment, the Visual Analog Scale (VAS) score in the observation group was lower than that in the control group, the menstrual volume was lower, and the menstrual duration was shorter (P < 0.05). The scores for menstrual flow obstruction, menstrual volume reduction, abdominal distension and pain, and menstrual blood clots with purple and dark color were lower in the observation group compared to the control group (P < 0.05). There was no significant difference in the adverse reaction rate between the observation group and the control group (P > 0.05). Conclusion: The combination of Shaofu Zhuyu Decoction and Thunder-Fire Moxibustion is effective in reducing pain and improving related symptoms of cold-dampness stagnation type of dysmenorrhea, and it is safe and efficient.
